The Barnett J4B is a small gyrocopter marketed in the United States by Barnett Rotorcraft for homebuilding. Originally flown as the J-3M with an open cockpit and fabric-covered sides, later versions have a fiberglass cockpit pod either partially or fully enclosing the pilot. Apart from the basic J4B, versions available in 2007 included the J4B2 (two seats side-by-side) and J4B2T (two seats in tandem). A J4B2 holds a coast-to-coast speed record in the United States for gyrocopters.
